ATRA® KEY Advantage

Presto offers two methods to connect GEOWEB sections. The ATRA Key and the Stapling method were compared in a side by side test. The results highlight the ATRA Key option as the clear advantage.

ATRA® Keys Compared to Stapling.

Stapling Operations Requires Compressor, Generator, Stapler, Staples

Disadvantages include site access difficulties, need for power source, rental equipment, down-time for reloading stapler & stapler jams.

ATRA Keys Require Only ATRA Keys.

No Additional Materials or Equipment Required.

Easy to handle in any site condition.

Material Requirements

Labor & Installation Rates (typical)

Laborers: Work independently

Equipment: No crew/equipment limitations

Installation Rates Achieved: Two workers on a slope connected four GEOWEB sections every 10 minutes (12 sections / man hour).

Laborers: Two workers required for every connection; work in tandem

Equipment: Must have one stapler/hose per 2 workers.

Installation Rates Achieved: Two workers on a slope connected two

GEOWEB section every 14 minutes (4 sections / man-hour).

3,400 Sq ft/hour (316 Sq m/hour)

8 GEOWEB sections/hour

1,144 Sq ft/hour (106 Sq m/hour)

1 per 2 GEOWEB sections

1.5 cents Sq ft ($15/Sq m) 2 x 25 = 50 / 3,400 sf = 1.5 cents/sf

2 x 25 = 50 / 316 m2 = $15/m2

2 per 2 GEOWEB sections

4.3 Cents / Sq ft ($47/Sq m)

2 x 25 = 50 / 1,144 sf = 4.3 cents/sf

2 x 25 = 50 / 106 m2 = $47/m2

Nearly Three Times Faster

ATRA Keys Stapling

ATRA SPEED STAKE

Design & Performance

Barbs and engineered stake shape adds increased level of holding force.

ATRA Speed Stake Equivalence:

16 inch ≥ 18 inch rebar/GFRP Anchor

20 inch ≥ 24 inch rebar/GFRP Anchor

* GFRP: Glass fiber-reinforced polymer

Specially engineered polymer blend material for highest strength and durability.

Corrosion resistant, non-metallic anchors suitable for use in acidic soils, saltwater applications or where extended design-life is required.

Flat polymeric head eliminates tire punctures on load support applications where permanent anchors are required (vs. rebar solutions).

High resistance to acids/bases/salinity.

Polymeric material delivers long-term durability in corrosive soils & conditions.

GEOWEB® ANCHOR

ATRA® SPEED STAKE

Fast, Efficient Anchors

One piece unit requires no assembly. No bending of rebar, attaching

ATRA clips to rebar, or sourcing rebar elsewhere.

Lighter than comparable rebar or GFRP anchors results in lower freight cost and easier handling on site.

Can be handled with bare hands (not recommended for GFRP an-chors due to potential for glass-fiber slivers/shards).

Pointed anchor tip easily punctures through geotextile underlayer better than rebar or GFRP stakes for faster installation.

Can be driven with pneumatic Hilti or SDS-compatible drivers for fastest, lowest-impact driving.

Barbed rod & stake shape for higher holding force with a shorter anchor length & faster to drive.

Flat head & double-sided flanged arms for fast anchor driving, maximum cell wall engagement and hold down power.

One-Piece Polymer Molded Anchors.

ATRA® Speed Stakes are engineered to provide maximum anchorage and resistance to sliding and uplift forces. Designed for use with GEOWEB geo-cells for crest, toe, and internal anchoring (with or without tendons), ATRA Speed Stakes are extremely fast to install, deliver a strong holding force and are highly resistant to corrosive environments.

Strength + Speed + Durability = Performance
