Pre injection helps in consolidating the strata ahead of the excavation. It helps in avoiding ground collapse, intercepting water paths and hence speedy and economical process of excavation.
Post injection involves consolidation of strata after the excavation activity. It is used for stopping water leaks and making the strata firm.
Alccofine Series 1100 due to its fine PSD technology penetrates deep in to strata & helps consolidate the same. Due to complete filling of fine fissures and pores; strata becomes water tight.
Soil Stability/Consolidation
Fine sandy soil strata need the consolidation to improve its soil bearing capacity (SBC). It can be done by injecting specially formulated micro fine cementitious grouts under pressure.
Consolidated soil strata allow safe and effective excavation of the substrate without the fall of adjacent soil.
Alccofine Series 1100 can be used for under pinning, permeation / percolation grouting, curtain grouting, etc.
Fissured Rock Grouting
Rock strata become unstable due to fissures or micro cracks. Interconnected micro cracks results in water seepage. This may lead to collapse & non stable strata.
Alccofine Series 1100 is an effective & economical solution for cavity filling, grade slab jacking, fissured rock strata stabilisation, etc.
It facilitates deep & effective penetration of highly fluid grout into micro cracks & fissures. These grouts do not need complicated equipment & are very user friendly.
Crack / Joint Injection
Cracks / joint is weakest portion of concrete structure. Crack needs to be repaired by filling the compatible materials with pressurised grouting technique.
Resin based grouts has markedly different coefficient of thermal expansion, creep, modulus of elasticity & hence are not compatible with concrete structures.
Normal OPC cement grout due to its larger particle size (d95 < 100 microns) cannot fill the crack completely.
Alccofine Series 1100 micro fine cementitious grouts with d95 < 20 microns are perfect solution for economical, high strength, compatible, environmentally friendly crack repair systems.
