Planter Repair

Waterproofing planters requires special care due to the weight and amount of water they carry when in use. This job required crack repair and patching, as well as the installation of a special liner made of fiberglass.


Crack repair
Traditionally speaking, two slabs of concrete cannot be glued together when there is a crack. This, however, is not the case through the use of our specialized materials which make monolithic 1.85 MPa adhesion possible. Not only can we repair concrete but also restore it to its original condition, even when wet. It works both on single cracks and concrete surfaces with multiple issues - no need for complete resurfacing. Such rehabilitation is even done on concrete surfaces that are combined with metal structures.

The following process is applied:

  1. Cracks are routed with a saw to create a V-groove to prep the area for repair.

  2. The crack is filled with Polyforce Plus Adhesive which ensures immediate and durable monolithic adhesion.

  3. The crack is patched with the polymer cement.

  4. Waterproofing Polyforce Plus Primer is applied over the area.

Patching
Under traditional repair methods, patching requires a minimum of two-inch demolition in the affected area. The use of our unique products, Polyforce Plus, and polymer cement, permits thin-patch applications, making the job much more cost-efficient and faster.

Our patching process is as follows:

  1. Delaminated and unsound concrete is removed.

  2. Polyforce Plus Adhesive is applied as an adhesive layer. Its impressive 1.85 MPa adhesive strength ensures monolithic adhesion.

  3. Within 40 minutes, the actual patch is applied. On very thin patches (less than a ¼ of an inch), Polyforce Polymer Cement is used; otherwise, regular cement.

Fiberglass Lining
As the last step of the rehabilitation process, fiberglass liner was installed in order to prevent future cracking that would normally be caused by  standing water.
