14. Liner lock down pins. Solution: Re-install and Geo-seal.

15. Installation of new Vents and drainage

16. Contaminated spray hose (with mineral spirits) Improper line flush

17. Geo-seal joint tape

18. Problem: Surface pin-holes. Improper application over coal tar pitch
Problem: Surface pin-holes. Improper application over coal tar pitch. No sealer previously applied.

19. Surface blow holes, from off gassing of cold tar pitch

20. Problem: Substrate not properly prepared Solution: Power wash any loose or poor concrete until they get a good firm substrate to adhere to. (may require a penetrating sealer if the concrete is too far gone.)

21. Trapped water blisters.

22. It is normal for some blistering to occur
It is normal for some blistering to occur. A small number of blister heads should be sampled and checked for proper membrane thickness.
If the samples have the required membrane thickness (80 mils nominal/60 mils minimum), then the remaining blisters should not be punctured or cut.
If the samples have less than the minimum 60 mils, then the area can either be re-sprayed to obtain the proper thickness.
Or the blisters can be cut out and the area re-sprayed or patched with Liquid Rubber Trowel Grade, to a minimum thickness of 80 dry mils over the cut-out area extending a minimum of three inches (3") beyond the cut.
