In this video, homeowner Nick uses GRA Secure Set Spray Foam to fill in the voids underneath his backyard patio, re-establishing support underneath the concrete, filling burrow holes and stopping further erosion and damage.
In this video, we used safety glasses, a 3/8 inch masonry drill bit, a hammer drill, some black electrical tape and if you want, an endoscope/borescope so you can see how large the void is. Here is the one we used: [ Ссылка ] . At the time of this video, we only had the 10 cu. ft. kit, which supports 10,080 lbs. per sq. ft. We now have a 16.6 cu. ft. kit, which will support 5,040 lbs. per sq. ft. If we had another project such as this, we would use this 16.6 cu. ft. kit, which gives you 66% more foam.
To buy the Secure Set Spray Foam, please go to www.secureset.net to see our 2 different kits available (200 kit, 16.6 cu. ft. Heavy Duty support and 120 kit, 10 cu. ft. Extra Heavy Duty support). Or you can call us direct at 405-672-8885 or email us at info@graservices.com with your shipping address and we will send you a quote, or go to [ Ссылка ] to place an order.
We no longer have the 14" extensions available, but for longer than 4 ft. spray with the mixing nozzles, you can use 1/2" CPVC pipe cut to the lengths you need, and some fiber reinforced strapping tape. See our document and video regarding the use of these extension pipes on [ Ссылка ] and the following document [ Ссылка ] .
