E.Proformance M

E.Proformance M is a redundant field-installed composite waterproofing, methane gas and vapor intrusion barrier for below-grade underslab and blindside vertical wall protection.

Designed specifically for waterproofing and methane mitigation projects being constructed within the City of Los Angeles, or Los Angeles County, E.Proformance M has the necessary approvals to effectively keep buildings dry and safe.

E.Proformance M has several benefits:

  • Redundant, with three layers of different waterproofing protection.
  • Provides chemical resistance to a wide range of contaminants found in soil and groundwater.
  • Seamless.
  • Fully bonds with the underslab and vertical wall.
  • Less weather sensitivity compared to comparable competitive systems.
  • Approved by the City and County of Los Angeles for sites impacted with methane gas.

Thickness: 96 mils
1st Layer: e.base 205
2nd Layer: e.spray
3rd Layer: e.shield 205

Designed specifically for waterproofing and methane mitigation projects being constructed within the City of Los Angeles, or Los Angeles County, E.Proformance M is has the necessary approvals to effectively keep buildings dry and safe. E.Proformance M is also resistant to volatile organic compounds (VOC’S) and aromatic hydrocarbons, and awarded a US Patent.

For below grade methane mitigation applications in the City of Los Angeles with shored walls, the underslab system extends from the underslab up the interior face the shoring wall for blindside protection.

For projects outside of the City of Los Angeles, the blindside vertical wall application E.Proformance M is not required. Contact EPRO for the proper assembly recommendation.

E.Proformance M is designed to be compatible with all types of building foundations, as well as, cast-in-place poured concrete or shotcrete foundation walls.
