The TRX® Swell Plug is designed to stop water entry through tie rod holes that are formed during the construction of poured concrete foundation walls. TRX® Swell Plug is a long-term two stage sealing device. By initially tightening to a snug fit, you stop any water flow immediately then the blue swell plug is water activated for a permanent seal.
You can purchase the TRX® Swell Plug nationwide to patch the holes in your concrete walls.
Most homes in the U.S. will have tie rod holes every 18 inches across the wall. Eight foot high walls have two rows approximately one foot from the floor and the upper row is approximately five feet from the floor. Ten foot high walls will have three rows with the first row approximately three feet high from the floor and three feet higher for each of the remaining two rows. Normally the upper and lower row of holes align vertically with each other. It is recommended that you observe the entire wall from a distance of five feet away after the location of the first tie rod hole leak. Viewing the wall in this method will help you see the others as they may appear as a small extrusion or irregularity in the surface of the concrete.
Properly expose the existing tie rod hole which is 5/8 inch diameter to a depth of three inches. Use a standard hammer by tapping on the area until the 5/8 inch hole is fully exposed and the edges of the hole are hammered away to a beveled edge. In most cases the front of the tie rod hole will have a 1/4 to 1/2 inch cosmetic covering of concrete. You can also take a standard screwdriver or dowel rod to finish exposing the hole to a three inch depth. If necessary, the area may need to be drilled out using a 5/8 inch masonry bit. If the tie rod hole has been repaired before, it will be necessary to drill the hole out using a 5/8 inch masonry bit.
After properly exposing the tie rod hole, remove any debris in the tie rod hole by flushing out with clean water or vacuuming.
Flush hole with water just prior to insertion of the TRX® Swell Plug.
Insert the blue end of the TRX® Swell Plug into the hole first and hand tighten by turning the coupler end. Once you have it snug, lightly tap the end of the coupler with a hammer until the coupler is flush with the wall. Finish tightening to a snug fit with a 3/8 inch socket. Do not over-tighten as it may cause the TRX® Swell Plug to fail.
The repair can be left as is or covered with a suitable hydraulic or comparable masonry product that can be found at home improvement stores.
The TRX® Swell Plug is not designed to be used when the tie rod hole has a wall crack located through the hole, nor is it designed to be used when the tie rod reinforcement hole is located within a honeycomb area of concrete (where excessive aggregate has cured in a given area causing seepage through the aggregate). The TRX® Swell Plug cannot be used on snap ties. Snap ties are small metal bars in the concrete wall that have been broken off. Sometimes this forming method is used instead of conventional 5/8 inch reinforcement rods.
The TRX® Swell Plug is intended to stop 5/8 inch tie rod hole leaks only. If the tie rod hole is located within a wall crack or honeycomb area, it will be necessary to have that area professionally waterproofed. Injection of water-activated polyurethane is recommended.
