We prepared a number of GRLWEAP studies to help select the correct equipment and verify driveability on steel sheet piles and tubular piles of different sizes at the Uig dock redevelopment. We then carried out Dynamic Load Testing with a BSP CX110. We were able to mobilise with only one day’s notice and carry out testing over a weekend. The report was delivered within two hours’ of testing.

We can test all types of piles. Here we’re testing bottom driven steel cased piles with a D500 drop hammer at a residential development near Reading. We carried out the CAPWAP analysis concurrently to speed up delivery of the report and keep the project moving.

With only a day’s notice we mobilised to carry out Pile Integrity Testing using the PET (Pile Echo Tester). We arrived first thing, used our battery powered grinder to carry out final preparation of the pile top, and collected high quality data quickly and efficiently.

We prepared GRLWEAP studies to help predict pile performance at a project in London. We have also carried out Dynamic Load Testing and CAPWAP analysis. We were asked to compare the results of a Static Load Test to the CAPWAP Simulated Static Load Test Curve. The results compare favourably, with less than 1mm difference between the predicted deflections at Working Load and 1.5x Working Load on the test pile and another pile, giving our client confidence in both test methods.

We tested all 114 CFA piles on a project in the Midlands at cast level. Testing at cast level means that the piling contractor can be confident that adverse integrity test results have not been caused by cracking from poor quality cropping. The piles still need to be cleared and with good quality concrete exposed. The test also requires a flat spot for the accelerometer and hammer to strike the pile top. Preparation like in the photo above is adequate, and allows for many pile to be tested in one visit.

Here we are testing some precast piles on a grain silo in Northumberland. We regularly test on precast piles for commercial and housing projects alike. The test is quick, the results are provided almost straight away and we can test tens of piles in a day.
