Water drainage issue

[Galvatron]

What can be done? Would I get positive results by going to the regional building inspector?

[starlinejobs]

Well since the wall is leaning already you'll have to brace it anyway. you can burst some holes in the wall and put some PVC in ( there's a name for it but I can't remember- soak-away??) it for the water to come on your side then channel the water into a drain.

weepholes.....

[streetbeastINC.]

spend your money and construct drainage...and a deep one concreted beofer the wall

[RapToR]

Let the wall fall if your land is empty

[Galvatron]

So visited the Building Inspector at the Regional Corporation, he indicated that they are understaff and the department basically has no 'teeth' to deal with these issues.

Starline, the wall already has weepholes, apparently the volume of water is turning the soil behind the wall into slush and the water is not flowing out fast enough. Raptor, any reason for letting the wall fall?

[skylinechild]

^^^ well if the wall fall and as you say the soil is turned to slush, wont be long untill his buildings has some serious cracks not to mention foundation problems...then he'd wish he HAD a retaining wall AND a proper drain....

ever head the story titled for "the want of a shoe"

OP is it possible for you to dig a trench just above the wall foundation and put down a perforated pipe wrapped with geo-fabric to allow the water to drain away from the wall?

[firstchoicett]

Hmmm give me PM of the location and contact number I will see what I can do for you.

[brams112]

report him to ministry of health,regional corporation and poilce.leave the wall alone just do the weep hole thing with the perforated pipe and geo fabric,seems that the wall weep holes are clogged with the same backfill material,,,

[nervewrecker]

what exactly is the problem here?

the leaning wall?

the water running into your place?

the mud and eroded material being deposited in your place?

tell me more, the water flows what direction when it enters your place? same or perpendicular?

your land is flat?

land cover?

average elevation?

any drains near the road to connect to if you do make a drain.

[brams112]

ohhhhhhhh seems the op help the man to build a wall to hold up the perp own property,,,let the wall fall if you cannot get the man to pay for his foolish ways,,,it may cost you cheaper,,,,

[Galvatron]

is geofabric what we call polythene?

if not is it readily available in hardwares?

Two different things there. Its usually bought from the company. Yellow pages will have more info. Also send user 'Rahtid' a PM. He would be able to do a site visit and give you some sound advice.

[badandy]

my .02 cents...
when the retaining wall was constructed,

1. once you backfilled behind the wall with granular material [to act as a sieve]
or used geotextile fabric [expensive]
2. used the correct depth of the pile or foundation
3. used correct sized and spaced weep holes

you should be ok

how long was the wall built and when did you first notice this problem....?

to everyone please use guttering and drains [pvc,concrete etc] for all rain,waste and surface water, to an appropriate outfall...

[streetbeastINC.]

if its waste water/roof water visit your local public health inspector at the cmoh office in your area....

OP if u could, post pics of the problem.

[Galvatron]

did some research on drainage for retaining walls, the perforated pipe looks like the best solution.

any suggestions on where this can be bought? what is the best granular material to use below the native soil?

btw what size of pipe should I use ? the wall is around 8ft high and 118 ft long

[brams112]

ur have to buy pipe and drill holes pal,normal 6'' pvc pipe,a spade bit and a power drill,the geofabric have to be the ones that water can pass through quickly,there is one that is a water barrier so be carefull which one you buy,3/4 stone or 1'' will do the job,,,,,but you have to remove the soil on the side of the wall that the job is being done,the fabric goes along the length of the wall,around the peforated pipe which have to be placed on a concrete surface,the drain off have to be at a angle to allow runoff,the stone is then used to cover the entire length of the pipe about a foot or more to allow filtering covered,,,with the soil,,,geo fabric i think may be bought by farfan in san juan,,,,

OP hold on. before you start to throw shovel and dig a trench u have some things to consider. soil type will determine how u gonna best utilise the perforated pipe. wall located north or south? i not sure about the macgyverism to make perforated pipes tho. it prolly could work. i dunno.
as there is retaining wall failure, u gonna have to be very careful how u go about trenching. what depth u looking at for the trench? pics OP pics.

DON'T DIG NOTHING YET.

Call Andre Ache at Pressure Concrete Plus Limited at 675-6019. His company offers something called Sheet Drain which you pin to behind the retaining wall and does the same thing as the granular drainage blanket. Check out the data sheet using the link below.

Sheet Drain

They can also install the sheet drain and core through the wall to install the weepholes at an appropriate elevation.

[Galvatron]

Rory, thanks for the link on the sheet drain, looks like the best solution.

Have you had any experience using it? Is native soil used to backfill the area, completely removing the need for granular material?

[Rory Phoulorie]

The sheet drain is covered with geotextile material. What the geotextile fabric does is prevent the fine material in the backfill soil from clogging the voids through which water will pass in the sheet drain. The need for granular material is negated with the use of the sheet drain.
