JakMat installation steps for grassed and aggregate surfaces

DECORATIVE STONE/AGGREGATE

1. Prepare the base ground:
Remove overburden and level ground (sub grade).
Allow a depth depending on end usage (see steps below).
NOTE: A geotextile fabric is recommended where a soft sub grade is present i.e. clay or deep topsoil. The fabric prevents upward movement of fine particles through the sub base layer which can cause destabilisation over time*.
*If unsure consult with an engineer.

2. Lay & compact the sub-base:
For vehicle traffic+ – Lay a sub base, GAP20 or GAP40*, of 100mm for light traffic (cars) and 150mm for heavy traffic (trucks). Compact well with flat plate compactor.
For foot traffic – Lay a sub base, GAP20 or GAP40*, of 50 to 100mm where soft subgrade. Compact well with flat compactor.
+For grassed vehicle parking areas our recommended use rate is for infrequent or overflow use, not daily traffic. For daily use an aggregate should be used.
*GAP20 or GAP40 is aggregate size of 20mm or 40mm down to fines.

3. Spread Sand:
Bedding layer (Optional):
Spread a 25mm layer of sand for a very level surface for mats lugs to bed into and light compact.
|
|
3. Spread GAP 7:
Bedding layer (Optional):
Spread a 20mm layer of GAP7 or sand for a very level surface for mats lugs to bed into and light compact.

4. Lay interlocking JakMat:
Lay mats while ensuring its interlocking is maintained.
NOTE: Standard hand or power tools can be used for cutting off mats as required. Also see "Laying Tips" on back page of this brochure. |

5. Fill the mat:
Fill the JakMat cells with a good quality screened topsoil and rake or screed so it is level with the top* of the mat. Avoid heavily compacting topsoil into the cells.
*Filling the cells only to the top allow for slight settlement back of topsoil into the cell and the reason this is important is once vehicle/pedestrian traffic begins the load is carried by the ribs of the honeycomb cell. This then avoids heavy compaction of both grass and soil into the cells causing grass and root damage and die back.

|
5. Fill the mat:
Fill the cells with the decorative aggregate of choice and compact. A 15-20mm topping layer is applied above the mat for 100% coverage and allows for settlement.
|
|
6. Sow the grass & let it grow:
Sow the grass seed and apply a light covering (2-3mm) of topsoil allowing the grass to germinate. Roll the entire surface and begin the watering campaign.
NOTE: Allow time for grass to become well established, preferably had its first mowing, before vehicle/pedestrian traffic is allowed on it. Also see "Grass Tips" on back of this brochure.
|
|
6. Compact the aggregate:
Compact the final surface and its ready for use.
NOTE: With settlement over time(3-6 months) a small amount of additional topping aggregate may be required.

JakMat Laying Tips
Lay JakMat with its longest (un-lugged) side along the straight edge. Lay the mats from right to left for the most effective laying result.
When applied on curved sections, only connect one side of the mat (only if entire connection is not possible).
When laying JakMatEnviro on uneven surfaces (e.g. around tree roots), pinning can be used to stabilise it and to facilitate the connection of the next mat.
Grass Tips
Grass selection is crucial in achieving the best results and consulting with a landscaper or retail specialist for a suitable grass seed mix is recommended.
Factors to consider are:
a) it needs to be a robust grass
b) suited to your soil type and climate
c) has the desired look and
d) knowing the maintenance required
Finally the single most important factor once your grass is sown in regular watering and keeping it moist at all times.
