Browse Forums Paving & Concreting 1 Dec 01, 2015 11:17 am On one side of our land we have a retaining wall belonging to one of the neighbour. The soil in our area is quite rich in clay, any amount of rain and you have sticky thick mud. To add to that, the neighbour has a garden patch running along his side of the retaining wall, which from the looks of it isn't properly drained. As soon as they water the garden patch our side gets heavy water log. I had few options in mind, but not sure which one I should go with. Option 1. Lowest cost Trench 40mm below his retaining wall's lowest point to create channels, slope them through the channels to 3 exit points which then slope towards 3 stormwater pits. Lay 40mm pebbles on top of it. Question: When there's water below the pebbles, and the soil is all muddy, am anyone walking over said pebbles can sink them in? It may just feel like walking over pebbles on a mushy land? Option 2. Same trench option as above, but concrete the trench to create channels 20cm wide 80mm thick. The water from the side of the retaining wall falls on to those concreted channels and drain out like the above layout. Put 40mm pebbles on top. Since it's concreted, there's no risk of pebbles sinking because of wet clay surface. Option 3. Highest cost Same trench option as above. Create a thinner concrete base for the RELN/Everhard. Place them, with the top of these on level with the bottom of the retaining wall. Channeling them away as above. Put 40mm pebbles on top. Can I get away with option 1 or will I have problems in the long run? Notes: The area isn't high traffic. The trench is usually on one side of the area, except the two exit channels towards the storm water pits (50cm length at 20cm wide). There will be stepping planks on the middle of the pebbles for people to walk on top of. 2 5821 I had a similar issue with my fridge not too long ago. It wasn't the same model, but the symptoms were pretty much the same: the compressor would start and then stop… 3 7516 |
