LL25 — Seal Coating
The topical copolymer seal that locks the surface down: cohesion, waterproofing and skid resistance, in one application.
The problem
An unsealed surface fails from the top down
Raveling and fretting
Braking, turning and repeated load pluck surface aggregate away grain by grain. The pavement degrades before the structure is even in question.
Water getting in
Every surface crack is a doorway. Water that gets in freezes, heaves, and turns a surface defect into a structural one.
The resealing cycle
Conventional sealers wear off and get reapplied on a loop. A seal that actually binds the surface changes the economics of maintenance.
The application design
A topical application, governed by a signed procedure
LL25 is applied as a topical coat over a cured LL30 base or an existing surface, by distributor truck. The product penetrates, sets and dries — the surface becomes a cohesive, waterproof wearing course.
- Typical application rate: 0.08–0.15 gal/yd² (LL/OPSDIRT Application Guide)
- Reopening to traffic: 24 h to 72 h per the Application Guide
- Procedure, curing and QC: SOP LL25 (Solecovia, Oct 2025)
The evidence
Tested where the surface is the whole point
Surface shear — USMC Cherry Point, 2017
Under repeated passes of a ~18,000 kg military MTVR truck — braking and turning included — the LL-TECH treated section showed zero surface tear or wear. The competing product tested broke apart. (LL-ATT-2026-EN-001 §3.2)
Skid resistance — USAF Nellis AFB, 2015
Structured U.S. Air Force evaluation program including skid resistance: LL-TECH met and exceeded the supervising military authority's operational requirements. (LL-ATT-2026-EN-001 §4.1)
Waterproofing — combined system
LL25 over an LL30 base: hydraulic conductivity of 3.62 × 10⁻⁸ cm/s (ASTM D5084) — water infiltration into the structure is essentially eliminated. (LL-TM-2026-001 §3.6)
Worth knowing: LL25 is a surface seal, not a structural layer — load-bearing capacity comes from the LL30 stabilized base (LL-TM-2026-002 §5.4). That is exactly why LL30 + LL25 together form a complete system.
Typical jobs
Where LL25 goes to work
- Sealed wearing course on residential streets and parking areas stabilized with LL30
- Protection of treated surfaces against water, freeze and raveling
- Surface closure after a repair or reclamation job (SOP LL25)
