The flooring in a house built three years ago started to sink – there was a gap between the floor and the skirting board. The interior walls were also starting to crack.
The problem
The analysis showed that the problem was caused by a layer of soil filling that was not properly compacted. Over time, the soil settles, and so does the floor and the shallow foundation of the non-load-bearing wall.
Solution
Upon arrival on site, the team reinforced the soil with geopolymer injections and raised the floor to its original level within a few hours. Injections under the wall foundations reinforced the soil and raised the wall to its original position.

Construction mistakes settled the floor

Symptoms
The owners carried out repairs in the house, but the floor continued to settle, and the gap between the floor and the wall grew wider and wider, and then the floor started to ripple.
The problem
The problem was caused by selecting the wrong thermal insulation material under the floor during construction and using a layer of concrete flooring that was too thin.
Solution
All the investigations were carried out, the technological errors were identified, and the floor assembly was reinforced. The floor was raised with the help of geopolymer injections.

Unstable soils under a boiler house
BEFORE
AFTER
Symptoms
The boiler pumping equipment had started to constantly vibrate. This led to particularly rapid bearing wear, increased maintenance requirements and equipment failures.
The problem
The pumps were built on a concrete floor without a separate foundation. The analysis of the situation revealed loose soils from a depth of 1.5 m. The concrete floor was unstable under vibrations and was an unsuitable base. Nevertheless, the pumps should have continued to operate without stopping.
Solution
The soils were stabilised and reinforced by deep geopolymer injections. The work, carried out in just a few hours, has already paid off, with the equipment running smoothly without vibrations, extending the equipment life.
