Frequently Asked Questions
- What waterproofing services does Blue Rock provide?
- Blue Rock provides facade joint sealing, masonry waterproofing treatments, through-wall flashing installation, expansion joint replacement, roof waterproofing systems (torch down, EPDM, cold-applied, liquid membrane), vault reconstruction and waterproofing, and below-grade foundation waterproofing.
- How does facade waterproofing relate to Local Law 11?
- Water infiltration through failing facade joints, deteriorated mortar, and inadequate flashings is the primary cause of masonry deterioration that leads to UNSAFE designations. Proper facade waterproofing as part of LL11 remediation prevents future deterioration and extends the life of the restoration work.
- What roofing systems does Blue Rock install?
- Blue Rock installs torch down (modified bitumen), cold-applied, EPDM, and liquid membrane roofing systems. We also handle drainage systems including scuppers, gutters and leaders, roof coatings, skylight installation, and roof deck construction.
- How do I know if my building needs waterproofing?
- Common signs include water stains on interior walls or ceilings, efflorescence (white mineral deposits) on exterior masonry, spalling or deteriorating brick and mortar, rust stains on facade surfaces, and wet basement or vault conditions. A free site evaluation from Blue Rock can identify the source and recommend the appropriate waterproofing solution.
- Does Blue Rock handle scaffold for waterproofing work?
- Yes. Blue Rock handles both scaffold installation and waterproofing work under one contract. No separate scaffold rental fees when we handle the waterproofing scope.
