- Create Tight Joints to be Filled
Fill larger voids with a mixture of small stones and gravel.
2. Prepare Foam
Prepare foam according to the manufacturer’s guidelines.
- Apply the Foam
Apply foam over the rock and gravel fill. Take into consideration that the foam will expand once dispensed. Use the foam along the stream edges between the framing rocks. Put foam anywhere else you believe water flow to be lost.
- Disguise the Foam
Allow a couple minutes for foam to dry slightly then place larger stones and gravel on top of the wet joints to help disguise it.
- Mold the Foam
Once the shell of the foam is cured enough to manipulate by hand. Hide any excess foam by molding it down into the joints
- Allow Time for Curing & Enjoy
Allow enough time for the foam to cure fully before resuming regular pond function.
