LL-TEQ Solutions / Erosion Control
Immediate stabilization of slopes and exposed soils — where seeding has no time to take and compliance won't wait.
The problem
A gullying slope becomes a compliance file
The compliance obligation
Sediment control, watercourse protection, certificate-of-authorization conditions: a gullying slope is a non-compliance that photographs itself.
Vegetation arrives too late
Hydroseeding and erosion-control blankets assume a growing season. On poor soils, steep slopes, or late in the season, vegetation does not establish in time.
Every rain costs
Sediment in ditches and basins, repeated slope repairs, complaints: untreated erosion is paid for in repeat work.
The LL-TEQ solution
LL25 sprayed on exposed soils
The LL25 sealant is sprayed directly onto slopes and exposed surfaces: it penetrates, binds the particles, and forms a cohesive layer that resists runoff — immediate effect, without waiting for a growing season. It works alone or alongside vegetation established later.
- LL-TEQ: loading and depth design, SOPs, technical presence, coordination
- The contractor or the client: execution of the works with their own equipment
- A compliance purchase: the solution is documented (application rate, manufacturer's tests, site report) for your environmental file

Runoff tested: no acute toxicity observed on simulated runoff water from an LL25-treated surface (EPA methods 2000.0 / 2002.0, Coastal Bioanalysts, 2013) — an argument that matters precisely in a sediment-control file.

The price
How the price is set
Every solution is quoted per m². The price follows from the loading design: the treatment depth and the product charge per m², set by our engineering design for your project. No published figure replaces a design — every quote is generated per project.
FAQ
Frequently asked questions
Is the effect really immediate?
The treated surface sets as it dries — in the manufacturer's documented tests, an LL25-treated surface was hard to the touch after 24 h of drying. The exact window depends on the weather and the application rate.
Is this compatible with vegetation establishment?
Yes — the treatment stabilizes the soil while vegetation establishes, or serves as the stabilization where vegetation won't establish.
On which surfaces?
Construction slopes, embankments and cuts, bared soils, mine closures, ditch banks — slopes accessible by spraying.
A slope to stabilize before the next rain?
