Does EA flood warning affect you?

The Environment Agency has warned that Britain’s flood planners must prepare for the worst on climate change, as its chairwoman, Emma Howard Boyd, said on current trends, global temperature could rise between 2C and 4C by 2100 and £billion a year would need to be spent on flood management, with some communities needing to move because of the risks of flooding.

The report from the EA has said that rising seas will swamp homes, with hundreds of key sites in England at risk of floods and that more should be done to encourage property owners to rebuild homes after flooding in better locations rather than just “recycling what was there before”.

The government said it will be seeking evidence for its own flood policy in the autumn.

Ms Howard Boyd, launching the consultation on the agency’s flood strategy, said government policy should ensure that all publicly-funded infrastructure is resilient to flooding and coastal change by 2050.

“We can’t win a war against water by building away climate change with infinitely high flood defences,” she said.  The agency expects more intense bursts of rain and continuing coastal erosion.  Ms Howard Boyd warned that climate change and population growth in England meant that properties built in the floodplain will double over the next 50 years.

The agency points towards research from the Cambridge Institute for Sustainability Leadership which suggests that losses on UK mortgages could also double if global temperatures increase by 2C and triple if warming hits 4C.

These would be insurance-related losses related to outcomes of climate change such as more extreme weather.  Ms Howard-Boyd said the government’s six-year flood programme had given flood and coastal protection “a shot in the arm”, but she warned that more will be needed.

Environment Minister Therese Coffey said: “Flooding and coastal erosion can have terrible consequences for people, businesses and the environment.  “That’s why we are already providing £2.6bn over six years, delivering more than 1,500 projects to better protect 300,000 homes.”

But she added that “the threat of climate change will mean an increasing risk and preparing the country is a priority for the government, and the nation as a whole”.

In a statement, Friends of the Earth said: “Smarter adaptation and resilience building – including natural flood management measures like tree-planting – is undeniably important.  But the focus must be first and foremost on slashing emissions so that we can avoid the worst consequences of climate chaos in the first place.”

Communities need to think about flood prevention and how solutions already on the market can protect their properties, such as the Marshalls CPM Redi-Rock™ flood walls that are designed and manufactured to suit a wide variety of flood water projects, as they are ideal for protecting commercial property and residential areas as well as larger infrastructure, highways, river ways and sea frontages.

Ideal where space is scarce or areas where water may rise to unusual levels, the flood blocks are both fast and easy to install and available in three aesthetically pleasing finishes so blend perfectly into the local environment.

As customer requirements are individual, so are the flood walls. They are designed to suit project specific size requirements by the Marshalls CPM Design team and are versatile enough to achieve height without compromising on strength.

Why is offsite the way forward?

With the construction industry constantly looking for fast, efficient, precast modular systems that decrease the number of health and safety issues on site, offsite construction is on the increase.

With products now being manufactured offsite under factory conditions and shipped to site and installed on the same day saving valuable man hours, installation costs, storage room and the need for skilled labour.

Marshalls CPM is leading the way in the manufacture of precast concrete offsite systems, offering water management products, flatpack systems and practical precast solutions based on sound design and engineering knowledge that are cost effective and a more sustainable approach to construction.

By offering offsite precast concrete products, customers have a great certainty over costs and programme timings, reducing the movement of vehicles on site and the Marshalls CPM technical team can offer help on your bespoke offsite solution.

Those winter storms are on the way – are you ready?

As we watched in horror the flooding from Hurricane Irma devastate parts of Florida, after causing more than $10bn (£7.6bn) in damage across the Caribbean, a figure which is still rising, we must look at what we can do to protect our infrastructure, both private and commercial from such horrors.

A 2012 BBC report stated that more than five and a half million properties in England and Wales alone were deemed to be at risk from flooding and that you can make permanent changes to reduce flooding and making these alterations can reduce the time and cost of recovering from flooding but can it look decorative?

Here, at Marshalls CPM we believe it can, as our Redi-Rock™ team has developed a flood wall that is doubled sided, with three aesthetically pleasing finishes, so looks great whichever side of the wall you are on and can be installed where space is scarce.

If you need a wall to look great when the flood water has receded as well as offering protection against flooding, then look no further, as our Redi-Rock™ flood walling is what you need.

So how does it work?

The flood walls are laid on a reinforced concrete strip foundation with starter bars into the hollow core. Wall reinforcement is then fixed as the blocks are laid. Once the wall has been completed, the core is filled with concrete to form the watertight barrier, protecting the surrounding areas from the flood water.

So what next?

We are happy to visit your site, help with designs and can even help with site installation; all you need to do is get in touch. How? Please call us on 01179 814500 or email redi-rock@cpm-group.com

Reducing the installation cost of manholes

Concrete pipeline systems manufacturers continue to innovate as the industry strives for improved pipeline and manhole construction quality and performance, delivering reduced waste, lower costs, faster build times and minimised environmental impacts.

Production techniques continue to advance and the use of modern logistics systems ensure excellent product quality and reliable service.

Responsible sourcing of raw materials from local suppliers ensures that cradle to site “pipe miles” is low and high use of recycled materials keeps embodied impacts to a minimum.

The use of modern, integrally-cast high performance seals helps maintain water tightness and integrity of joints.

The design flexibility of concrete pipeline systems means that many special features can be incorporated in the factory and simply placed into position on site. These “offsite solutions” can replace lengthy in-situ operations, thus improving site safety and product quality, reducing waste, speeding-up installation and reducing costs.

An excellent example of an offsite solution introduced recently is a concrete manhole system, packed with many benefits that will satisfy designers, contractors and operators alike. The new manhole design offers:

Reduced construction time
Decreased installation costs
Improved safety on site
Superior quality
Watertight system
Reduced carbon footprint

Concrete Manhole Construction

Traditionally, manhole construction has required the base to be formed in-situ where building of the channel, connections and benching occurs in the trench, often in wet and unpleasant conditions. The process can take around 40 hours per manhole and is not always successful, particularly in terms of leakage where egress of waste water can lead to contaminated groundwater and ingress can contribute to the common problem of overloaded sewer networks plus increased energy usage and running costs at treatment works and pumping stations.
Concrete Manhole Design

The new concrete manhole design comprises a precast concrete monolithic base unit, complete with channel and benching with predetermined combinations of inlet(s) and outlet and a new design of chamber ring with watertight, flexible joints and no lifting holes, thereby removing points of possible leakage.

Both base units and chamber rings are made with thicker, stronger walls. The robust design means that the requirement for a concrete surround is eliminated, unless specifically required. The excavation is backfilled sooner and there is less need for men to work in confined spaces. This reduces time spent in the excavation, further improving site safety and reducing installation costs.
Concrete Manhole Installation

Installation of the whole system is speedy and efficient. Once in position, wet trades are eliminated, formation of benching on site and sealing of lifting holes is avoided and follow-up operations can start immediately. Field trials indicate that time savings of over 30% can easily be achieved and costs reduced by well over 10%, particularly when installed without a concrete surround.

Enviromental Advantages

The system also yields environmental advantages as less concrete is used, there is less waste and less excavated material is disposed to landfill. An annual saving of over 22,000 tonnes of CO2e is estimated in the UK if all manholes manufactured by members of CPSA changed to the new precast base system.

The quality of material and finish is well above that normally achieved on site and the full system is manufactured under factory conditions by third party certified companies to ISO 9001 quality management system. Products are Kitemarked to BS EN 1917:2002 and BS 5911-3:2010Concrete Manholes and Inspection Chambers and tested under laboratory conditions.

UK Water companies have embraced the new precast manhole base system and given their acceptance to use the design for new projects in lieu of traditional in-situ construction and full acceptance is anticipated throughout the UK
