The present invention discloses a method for microbial Grouting basement concrete structures subjected to vertical cracks in the wall using the method of filling the inside of the seam closed fracture, including drilling, hole cleaning, surface sealing cracks, bacteria and nutrient solution preparation ...
Basements/Attics: Pipe and duct penetrations Plumbing stacks and shafts Wall cracks Along the sillplate and floor/wall junction APPLICATION INSTRUCTIONS Remove the dust, greasy dirt on the surface before construction. Spray a little water on construction surface ...
The EPA and many other professionals know the I/I comes into sewer systems via cracks, improperly sealed manhole covers, joints, manhole chimneys, manhole bases, damaged pipes, storm water basins, and sump pumps illegally tied into public sewer systems. However the main source of I/I is manho...
Waterproof concrete walls, like any basement waterproofing system, can leak. Typically, these systems fail due to: defective detailing or workmanship at kicker joints; settlement or drying out cracks allowing water to penetrate through the retaining wall; and ingress of water through and around servic...
Each stud bay in the partition effectively becomes a little chimney. Stack effect draws in air at the bottom of the wall plates and pushes it out the cracks into attics. Holes for electrical wiring andplumbing ventscompound the leakage. ...
The medium-sized air leakage hole shown here is where a furnace flue goes from the basement through the first floor on its way to the attic. See that fluffy yellow and black stuff? That’s a clue that tells you two things. It’s blown fiberglass insulation. How’d it get there? It ...
patch and profile any joints, seams, cracks, holes or rough areas. Products are packaged separately because different mixes are required for different applications. For example, a 1-inch diameter caulk bead of LRB/TAV (1 part TAV, 2 parts LRB) mixture is applied where the wall meets the ...

Sealing imperfections could arise during or immediately after the sealing operation itself (i.e., by incomplete or uneven displacement of drilling mud, insufficient bonding of the sealing material to the borehole wall, development of cracks due to thermal or mechanical stresses), or later due to ...
