Frequently Asked Questions
What below-grade work is Sikalastic HLM 5000 GC used on?
Exterior below-grade and between-slab waterproofing on concrete, masonry, and incidental metal. Typical work includes foundation walls, below-grade slabs, plaza decks, planters, parking garages, split slabs, walls, and culverts.
What green-concrete timing does Sikalastic HLM 5000 GC allow?
It may be applied as early as 72 hours after the concrete is poured, or as little as 24 hours after forms come off. It can also cover damp concrete within the published temperature window.
What coverage does Sikalastic HLM 5000 GC deliver at 60 mils?
Approximately 25 ft2/gal at 60 mils DFT for the standard system. High-build rates are approximately 18 ft2/gal at 90 mils and approximately 13 ft2/gal at 120 mils. Actual coverage varies with substrate finish and porosity.
What crack bridging does Sikalastic HLM 5000 GC pass?
The 60 mil standard system passes ASTM C 1305 crack bridging at 1/16 in with no loss of bond or cracking after cycling. The 120 mil high-build system passes 1/4 in on the same test.
What service temperature range does Sikalastic HLM 5000 GC cover?
Published service temperature is -40 F to 120 F. Apply when air temperatures are 40 F to 90 F unless Technical Services approves colder work.
What protection does the cured Sikalastic HLM 5000 GC membrane need?
Protect coated surfaces from puncture with protection board or drainage mat before backfill or topping. Place protection as soon as possible after cure, and no later than 90 days after application.
