Product Specs

Recommended UsesDense/crushed base with sand bedding; Clear/open graded base with chip bedding; Concrete slabs, wet cast, natural stone; Residential/commercial pedestrian; Driveways with drive grid or bilateral geogrid
Yield — Open Graded Base1 Perma Pak + 50–60 lb bag concrete yields 12–16 ft of edging
Yield — Dense Base1 Perma Pak + 50–60 lb bag concrete yields 17–21 ft of edging
Mix Ratio1 Perma Pak per 50–60 lb bag; 3 Perma Paks per two 80 lb bags
Blending/MixingBlend Perma Pak with dry concrete ≈ 1 minute; add manufacturer’s water; mix to thick oatmeal consistency
Installation HighlightsRemove bedding layer along edge; Distribute evenly; Trowel a ~36° pitch; Stay low: on 60 mm paver come up ~1/2 in; 70 mm ~3/4 in; 80 mm ~1 in; Compact pavers while edge is wet for best performance; Finish grade with topsoil/mulch/stone
Driveway SetupUse ≥4 ft wide geogrid; Place grid with ~6 in beyond edge and ~3 ft 6 in under pavers; Install bedding, pavers, remove bedding at edge, lift 6 in grid, install edge
Cold WeatherAdd 3/4 cup calcium chloride per 50–60 lb concrete blend to accelerate cure below freezing; use insulation tarps/native soil to retain ground heat
Base NotesDense/Crushed: sand leveling over compacted 0–3/4 in base; Clear/Open: ASTM No. 9 leveling over compacted 3/4 in base

Features

  • Extreme flexural strength:
    Makes standard concrete approximately 783% more flexible
  • Water Stop Technology:
    Waterproofing throughout the entire concrete volume,
    Improved resistance against hydrostatic pressure,
    and the ability to seal non-moving cracks up to 0.016 (0.40mm)
  • Shrink Control:
    Greatly reduces cracks related to drying and autogenous shrinkage,
    substantially improves impermeability, improving concretes durability & life cycle.
  • Void Reduction:
    Dramatically increased compressive & flexural strength,
    reduces permeability to increase the life of concrete
  • Macro Synthetic Fibers:
    Reduces shrinkage & settlement cracking. Improves residual strength of concrete,
    improves impact resistance, and enhances the durability of concrete.
  • All the benefits of Perma Edge paver edging, now in a 1lb bag

A 1 lb concrete additive engineered for paver edging. Blend with water and job-site concrete to create fast-install, durable support for patios, walkways, and driveways.

Yes. The Water Stop technology improves resistance against hydrostatic pressure and can seal non-moving cracks up to 0.016 in (0.40 mm).

No. It’s designed to be blended into dry concrete at the job site first, then water added.

Immediately, while the edge is still wet. This improves bond and long‑term performance.

Both are supported. Expect yields of 12–16 ft on open graded and 17–21 ft on dense base per 50–60 lb bag + 1 Perma Pak.

Concrete Mixes FAQs

One-part resin sands handle pedestrian areas and narrow joints. Two-part epoxy mortars are built for medium to heavy vehicular traffic, driveways, and wide joints. Concrete additives boost standard bagged concrete for custom paver edging, while trass bedding mortars and bonding slurries create stable, permeable bases for heavy stone or porcelain.

Most resin and epoxy joint compounds can be installed on damp paving and during light rain. Bedding mortars, bonding slurries, and concrete edging mixes need dry weather during application to set correctly.

Higher temperatures speed up curing and shorten your working window to about 30 minutes, so work quickly and clean surface residue off immediately. Cooler temperatures slow curing down. Do not apply mixes on frozen ground or when surface temperatures fall below 37°F.

Self-compacting joint mortars flow into voids naturally when worked across the surface with water and a squeegee. This eliminates air pockets and builds a tight bond without needing mechanical compaction equipment.

Keep the paving surface wet during application, clean off excess material within 5 minutes, and rinse thoroughly. Sweep away remaining fine particles with a damp coconut fiber brush without pooling water. Any slight residual film will weather away naturally under UV light and foot traffic.

Permeable bedding lets water drain freely to the sub-base, preventing standing water, efflorescence, and freeze-thaw damage beneath natural stone, pavers, or tile.

Most joint mortars and bedding systems accept foot traffic after 24 hours. Wait 3 to 7 days for full curing before opening the area to heavy vehicular traffic.

Adding an admixture package to dry, standard bagged concrete introduces synthetic fibers, shrink control, and waterproofing. This increases flexural strength by over 700%, helps seal micro-cracks, and prevents edge breakdown along driveways and walkways.

Apply a bonding slurry to the back of porcelain, natural stone, or pavers before placing them into a fresh mortar bed. This wet-to-wet application creates a high-strength monolithic bond that keeps tiles and pavers from popping loose under heavy loads.

Use clean, washed aggregate between 1/16 in and 1 in in diameter, including glass chippings. Stones can be slightly damp, but dirty, dusty, or soaked aggregate will prevent proper epoxy bonding and weaken the final surface.
