For situations where there is some movement in the structure, urethane injection is used. This method forces the chemical through the cracks by use of a pump. The urethane reacts with the water in the cracks to produce a dense, flexible closed cell foam stopping off the water. If the structure is stable we can carry out repairs using crystalline technology whereby water in a crack reacts with the product causing crystals to grow and fill the pores within the concrete. The crystals in the product will continue to grow or be reactivated in the presence of water. These repair methods have the benefit of being able to be carried out from the inside of the structure meaning expensive excavation or replacement of patios are not required. The repairs can also be carried out in the presence of water, so waiting for dry conditions is not necessary. Reaction time can seal active leaks in minutes. Grout is flexible and rated food safe, as such it is ideal for sensitive water storage leaks of all types.
