Abstract
A laminated mat for growing lawns or other vegetation on soil comprises a base sheet of water pervious, bio-degradable web material. Joined to the base sheet by an adhesive binder is a bed of seeds and dried, compressed peat particles. Secured to the bed of seeds and peat particles is an upper laminate comprising a fibrous, porous veil which protects and retains the bed therebelow. The upper veil is water pervious to pass water therethrough to the bed of peat particles and seeds. The bio-degradable veil also easily expands to retain the wet, expanded peat particles and the seeds entrained by the peat particles and the veil.
Claims10
An improved laminated mat for growing vegetation on soil, comprising,
- an outer lower base sheet laminate of water pervious web material, said material being quickly biodegradable to become part of the soil after coming in contact therewith;
- a bed of seeds and dried, compressed peat particles, wherein said peat particles are treated to remove dust entrained therewith, means for adhesively securing said bed to said base sheet, said particles being expandable upon wetting to surround and form a mulch for said seeds;
- and
- an outer upper veil laminate of fibrous, unwoven, porous web material and means for adhesively securing said veil to said bed, said veil comprising means for expanding with said expandable peat particles and retaining said particles and seeds integrally in said mat after biodegradation of said base sheet, said veil being slowly biodegradable to become part of the soil after germination and rooting of said seeds.
An improved laminated mat for growing vegetation on soil, comprising
- an outer lower base sheet laminate of water pervious web material, said material being quickly biodegradable upon wetting,
- a bed of seeds and peat particles, said peat particles being formed of peat which is dried, compressed to form a dense solid mass, said solid mass being broken into particles which are screened to select a predetermined particle size range,
- means for adhesively securing said bed to said base sheet, said particles being expandable upon wetting to surround and form a mulch for said seeds;
- and
- an outer upper veil laminate of fibrous, unwoven, porous web material and means for adhesively securing said veil to said bed, said veil comprising means for expanding with said expandable peat particles and retaining said particles and seeds integrally in said mat after biodegradation of said base sheet, said veil being slowly biodegradable to become part of the soil after germination and rooting of said seeds.
