Pressure Grouting

Small volume placement of cementitious and resin based grouts in specialist of difficult situations

Infilling of spaces under machine bases, annular gaps around pipe inserts, voids in steel fabrications

Injection of cement based grouts into or around masonry structures to strengthen cavity or rubble wall construction, stabilise loose fill, prevent movement and improve structural integrity

Use of small to moderate volumes of foamed concrete or grout to fill redundant drains, sewers and manholes or to fill voids beneath redundant bridges or subways

Prevention of ground water ingress into precast segmental concrete manholes, shafts, culverts and tunnels

Interstitial grouting of brickwork and masonry walls, bridge arches, culverts and tunnels using aqua reactive resin grouts

Remedial work to make good the effects of washout and other disturbance caused by ground water in masonry bridges, culverts, tunnels, shafts, basements, man holes

Grout materials used are conventionally pre-bagged, cement or cement:pfa mixes, mixed mechanically and delivered to the point of application using mechanical worm pumps.
