Ground Strengthening

For centuries mankind has realised that dwellings are best built on firm ground above flood level. Historically, this is lead to castles, forts and temples all being built on high dry rocky ground.

Unfortunately with ever increasing population and the construction of more and more buildings in the last century, mankind is now building warehouses and factories on what was once soft farm land or even flood plain land. This frequently leads to settlement issues for the modern factory owner / operator. 

Even 50 years ago, prior to modern high bay warehouses and robotic production lines, 50mm of settlement could be worked around, but today it is a different issue and modern warehouses and factories need solid floors complying to FM2 flatness standard which is 10mm in 3 metres in any direction. High bay fork trucks often lift 7.5 metres vertically on a wheelbase of 1.1 metres, so a 7-8 mm floor dip can cause a mast to be out of plumb by 50-60mm, leading to instability and toppling.

How to strengthen ground after building subsides?

Uretek India has the answer-

At Uretek India we specialise in injecting expanding structural geo-resins.  Geo-resins are expanding PU resins that have been formulated for strength, density, rate of expansion, volume of expansion and the ability to chemically react in wet soils.

Uretek India senior management has more than 40 years combined experience and this technical knowledge coupled with skilled, factory trained installation field technicians supervised by qualified site engineers means that we give our customers excellent service with well engineered successful outcomes.

The basic principle of the Ground Strengthening Technology is:

1. Identifying the weak soils
2. Drill a matrix of small holes and insert small bore injection tubes to discharge into the weak strata
3. Inject as a liquid (into the weak soils) a 2 part geo-resin which chemically reacts and expands 1-25 times during the reaction
4. This expansion densifies the weak strata and is ultimately limited by the confinement of overburden and the strengthen of the injected soil itself
5. Further injections expanding directly under foundations or slabs will induce lift.
