Saving you time and money on your Construction Projects.

Ground conditions, settlement, groundwater, heave, excavation requirements and the constraints of the development can all influence whether a piled raft is the right solution and how it should be designed.

In our latest article, we look at the engineering behind piled raft foundations, including ground conditions, pile length, voided and non-voided rafts, and how our projects have demonstrated these variations in practice.

The foundation design includes 23 piled rafts serving 24 units, covering approximately … more

Today is National Tradesmen Day, a good excuse to give a shout-out to the people who make things happen on site. 👷‍♂️👷‍♀️

From the first foundations going in to the final details, construction is built on skilled people doing their jobs properly, day in and day out.

Thank you to the tradespeople who keep the industry moving and … more

Our latest case study looks at our project in Suffolk which was within a mapped Tree Influence Zone. Our geotechnical review and testing showed that a non-voided piled raft solution could be used, despite the trees.

@Matthew Homes needed foundations for six houses and a garage, around 400m² of structural foundations across five residential piled rafts and a further raft for the garage. A total of 6-week construction programme to structural slab … more

We’re getting started at Otterham Quay Lane in Rainham, Kent this week.

This one is for @Stonebond, with the development being built for @West Kent Housing Association.

The site was previously a commercial pear orchard, and over the next 14 weeks we’ll be installing 34 piled rafts to … more

Raft or strip foundations? It depends on what’s happening beneath the building.

Strip foundations can be a straightforward and economical solution where ground conditions are good and consistent.

But introduce variable bearing capacity, Made Ground, deeper excavation, groundwater or challenging soil conditions, and the scope can change quickly. … more

Friday Throwback: When the ground conditions call for more than a standard approach.

Back to Elsea Park, Bourne, where we delivered the foundation package for 141 @Bellway Homes.

The site presented a combination of challenges, including Made Ground, variable underlying geology and potential tree influence, making heave protection an … more

Building on Made Ground?

Made Ground can vary significantly across a development, which can make foundation design more complex than it first appears.

Here are 5 things to consider:

1. How deep is the Made Ground?
Its thickness can vary … more
