It’s the end of 2023, so we’re back once again with a statistical review of Constructive Evaluation’s year.

When it comes to foundation investigations and ground sampling, the are many methods Constructive Evaluation can employ to achieve desired results. One such technique is cable percussion drilling. This efficient practice is widely used in the construction industry for its ability to reach deep below the surface and provide invaluable information about soil and rock conditions.

Construction projects of any scale require a strong foundation to ensure the safety and structural integrity of the built environment. Geotechnical investigations play a crucial role in the early stages of construction, helping engineers and designers gain valuable insights into the ground conditions on which a project will be built

Trial pits (sometimes known as foundation pits, trial holes & trial trenches) are Constructive Evaluation’s most common geotechnical works. But what exactly are they and why do we use them?

This year marks Constructive Evaluation’s 30th anniversary. To celebrate the occasion, we thought we’d share with you the history of the company

In a change of pace from our usual blogs on the services we offer, this month we thought we’d review Constructive Evaluation’s year.

Our geotechnical team have been hard at work in London this week carrying out a plate load test. But what is a plate load test?

Window and windowless sampling are methods of soil extraction that retain the various horizons of the soil, so that they may be analysed, measured and profiled.

This week we’re going to be looking back at a dart rig job we undertook in 2019. This particular job was interesting because it highlighted the challenges of working in old buildings

Constructive Evaluation was recently commissioned to carry out a Site Investigation to an island situated on the River Thames. Before we could carry out our investigations, we first had to get to the island

With the improved weather conditions spring usually brings, the end of March is the best time to perform a percolation test. Find out why you might need one

Constructive Evaluation were recently commissioned to undertake an unusual Ground Investigation project – providing design parameters for the construction of a new shipping jetty over the River Thames

Constructive Evaluation is pleased to announce that we are participating in the Kickstart scheme.

Constructive Evaluation were recently asked to undertake some boreholes at a site in West Sussex where access was a little narrow.
