SIREWALL World Records

We acknowledge that there are many ways to measure the best modern rammed earth on the planet and here are some:

TALLEST:

30m (100′) tall SIREWALL tower
18.25m (60′) tall SIREWALL stair well
15.5m (51′) tall SIREWALL building spine

Tallest competitor’s wall is 8m (26′). If anyone knows of a taller wall please inform and we will change this

STRONGEST:

Strongest average strength using no more than 10% cement:

Skanska project, Seattle, WA ~50 MPa
Van Dusen project, Vancouver, BC ~42 MPa
Lalit Mangar project, Dehi, India ~30 MPa
Average competitor’s strengths are 2 – 7 MPa

LONGEST WALL:

Perimeter wall, Telenor 345: 1 km x 3m tall

STRUCTURAL ACCOMPLISHMENTS:

Deepest back fill: 30′ (9m)
Many competitors require their rammed earth to sit on a stemwall so it doesn’t even venture below grade.

Longest lintel: 41′
Heaviest hanging RE section: 100 tons

DELIVERY ACCOMPLISHMENTS:

Most production in one day: 110.5 cu yd (84.5 m3)
Largest gang form panel: 32′ x 28′ = 896 sq ft
