Water-absorbing, Crosslinking Polymeric Gel for Preventive and Remedial Grout Injection
Kisgel P1 is a one-component injection gel/chemical formulated from crosslinking polymeric and water-absorbing technology. It absorbs and reacts with water (from leakages in the structure) to form a chemically-resistant, resilient and tough gel-like material that instantaneously arrest water seepages. When cured,it has been proven to be resistance and remained undamaged by aggressive chemicals such as Xylene, Diesel and Sulphuric acid commonly found in tunnels and substructures. Furthermore, in the presence of these chemicals, it will retain its ability to expand and acts as an active plug in the cracks. The gel has also been tested for and subjected to heat of up to 70°C, with positive results of having very little effect and no signs of degradation.
Its absorption rate is extremely robust – it is possible to chemically-combine with water from a fraction (0.2 times and lower) to 10 times of its volume. The gel structure varies from a soft gel (in presence of higher amount of water – 10 times) to a resilient gel (water about 0.2 times), ensuring a complete sealing method that quickly stops water leakages and plugging the end with the use of only one single material.
Another important feature is its controlled and consistent gelation time with water, of about a minute upon contact. This will allow the resign to be injected and flowed into adjacent and connecting cracks which are not leaking yet, and sealed them even before they pose problem later.
Summing all the properties together, Kisgel P1 sets itself apart from other repair material as a lasting and easy-to-use solution for restoration or remedial work in structures with cracks of mild to serious leakages. It is applied with a a single injection pump, such as KST P58. There is no need for complicated mixing of accelerators and catalysts in conventional acrylate-based gel materials.
