we have diversified and have successfully executed various projects on Underground seepage control, protection and rehabilitation of old concrete, repair to ballastless tracks under limited traffic block. These are highly specialized fields of activity where not many organizations can authentically claim to...
Within 4 months of the grouting I started experiencing the same problems, i.e., stairstep cracks in exterior wall, cracking tile, cracking ceiling, cracking pool deck coming up in chunks, brick facing separating from block walls. I am also completely surrounded by confirmed sinkhole properties....
This machine can be widely used in the anti-seepage treatment of underground caverns, foundation pit walls, dams, etc. and the repair of concrete defects. It is suitable for door frame filling, fireproof coating, concrete repair and insulation system engineering. It is an ideal modern constructio...
They are also very suitable for repair work of wet cracks in concrete structures. Pedestrian Tunnel Rehabilitation, Ottawa, Canada, 1989. Persistent seepage had been a serious nuisance in the pedestrian tunnel between the central block and west block on Parliament Hill in Ottawa. Water bypassed ...

According to Eton aerated concrete block with one-line and two-line cavity with different strength axle pressure and shearing test of through structure are made in order to understand basic properties of aerated concrete block as well as the influences of mortar strength and block strength onmasonry...
Shear Strength of Concrete Block Triplets: An Experimental Investigation Under Varied Grouting and Precompression Conditionsdoi:10.1007/978-3-031-73310-9_12Masonry shear walls serve as essential lateral load-resisting members in many structures. The shear strength of masonry walls is a critical ...
A shaped brick comprises concrete block, paving stone, and outer layer containing water, hydraulic binder and aggregate. The aggregate is photocatalytic. Independent claims are included for the following: (1) joint material; and (2) dressing of stones.TISCHER, WERNER, DR....
Canadian and American standards provide the compressive strength of concrete masonry assemblage as dependent on compressive strength of blocks, mortar type, and percentage of grout. It is common in construction to sporadically place non-standard units in masonry walls. Moreover, grout can have many ...
plastic film; the slurry gathering holes are drilled holes formed in front cast block concrete, penetrate through a concrete bonding surface and then extend into the front cast block concrete; multiple slurry outlet grooves are formed in the pipe walls of the outlet ends of the grouting branch ...
