Work as advertised and make putting up 20mil liner on the walls much more secure and professional. Use a professional type hammer drill (I used this project as an excuse to purchased a mid-level Bosch rotary hammer)and you will be done in no time. After inserting the pins by hand/thumb, I used my soft rubber mallet to give them a nice little tap. Be a pro and don't leave this step out.

Easy to install. Great product.

Worked perfectly.

The foundation pins worked great. I installed one pin every two feet along the perimeter wall and within two inches of every corner. Three pins were installed on each 8"x16" cinder block pier. They give a nice professional finished appearance.

Pins work great! Wide head. Fast shipping.
