'water proofing'

Waterproofing Bore packing A waterproofing technique that involves using non-shrink grout to fill gaps between the core cutting and the plumbing pipe Steps in bore packing Mark the core cutting location on the floor Cut the core with a diameter slightly larger than the pipe Roughen the side face of the core cutting area and pipe for better bonding Apply a bonding agent Use shuttering to hold the bore packing material Position the pipe and check its location and verticality Fill the gaps with non-shrink grout Perform a ponding test or flood test to check the packing

Ultimate performance and model code-compliant design for virtually any concrete-to-concrete and steel-to-concrete connections – ETA assessment for anchoring inc. C1 and C2 seismic and ETA for rebar inc. fire and seismic The first epoxy mortar qualified according to EAD 332402-00-0601 for concrete-to-concrete connections – rigid connections can now be designed and executed with post-installed rebars without splices according to the newest design method TR069 Suitable for the toughest jobsite conditions – works even in diamond-cored, wet or underwater holes, extremely deep injections, large diameters and at temperatures down to -5°C / 23°F Improved bond strength in the most demanding applications – such as cracked concrete and seismic C2 conditions Easier to specify and order – use PROFIS Engineering to design baseplate connections and PROFIS Rebar to design concrete-to-concrete connections according to EC2, TR069 or the Hilti Design Method

Wet-cutting diamond blades can have either teeth or a smooth, continuous perimeter. Water not only helps cool and lubricate the blade but also keeps the dust down. These cut the fastest and cleanest, but they require a special saw that can both distribute water and be safely used around it. As a make-do option, you can plug your saw into a GFCI-protected extension cord and have a helper carefully direct a small stream of water just in front of your saw as it cuts. If you have just one big project, you’ll save money and time by renting a wet-cutting saw/saw blade combination. Rental centers carry walk-behind saws for sawing or scoring concrete slabs, as well as a variety of hand-held saws for other tasks.
